Browse A/C Compressors
We supply new and remanufactured air conditioning compressors for commercial properties across the UK and worldwide. Our range includes models from leading manufacturers such as Copeland, with options offering a wide modulation range from 10% to 100%.
An A/C compressor is a key component of an air conditioning system. It compresses refrigerant gas to increase its pressure and temperature, moving refrigerant around the system and driving the cooling cycle. This allows commercial air conditioning systems to remove heat from indoor spaces and maintain the required temperature.
Our range includes AC compressors suitable for a variety of commercial cooling applications. Copeland units offer features such as charged POE oil, low TEWI, low sound and vibration, and low oil circulation rates, depending on the model.
At Diamond Compressors, we supply compressors throughout the UK and worldwide. UK customers can also benefit from our lift & shift service, helping to safely handle and move compressors when required.

About Air Conditioning Compressors
Air conditioning compressors are responsible for circulating refrigerant through air con. They play an important role in the cooling cycle by compressing refrigerant gas and helping it move between the evaporator and condenser.
The compressor draws in low-pressure refrigerant gas from the evaporator. It then compresses the gas, increasing its pressure and temperature before sending it to the condenser. Heat is then released from the refrigerant before it continues through the system and returns to the evaporator.
This process repeats to provide continuous cooling and temperature control.
Air conditioning compressors are available in different types, including:
- Scroll compressors, which use two spiral-shaped scrolls and have fewer moving parts than many other compressor designs.
- Reciprocating compressors, which use pistons to compress refrigerant gas.
- Screw compressors, which use rotating screws to compress refrigerant and are often used in larger commercial and industrial systems.
The most suitable compressor depends on the air conditioning system, required cooling capacity, refrigerant, operating conditions, and level of control needed. Some systems may also use control units or a control valve to help manage compressor output and system performance.

Air Conditioning Compressors FAQs
An air conditioning compressor is a mechanical component that compresses refrigerant gas and circulates it around an air conditioning system. It increases the refrigerant pressure and temperature, helping the system remove heat from indoor spaces.
The compressor is one of the main components in the cooling cycle and must match the system’s refrigerant, capacity, and operating requirements.
An air conditioning compressor draws low-pressure refrigerant gas from the evaporator and compresses it into a higher-pressure and higher-temperature gas. The refrigerant then moves to the condenser, where it releases heat before continuing through the system.
The refrigerant returns to the evaporator, where it absorbs more heat. This cycle repeats to provide continuous cooling.
Air conditioning compressors circulate refrigerant through an air conditioning system, removing heat from indoor spaces and maintaining the required temperature.
They're commonly used in:
- Commercial air conditioning systems
- Office buildings and retail premises
- Hotels, restaurants, and other hospitality settings
- Industrial and manufacturing facilities
- Larger cooling and temperature-control systems
The compressor works with other components, including the evaporator, condenser, and expansion valve, to complete the cooling cycle. The right AC compressor depends on the system’s cooling capacity, refrigerant, and operating conditions.
An air conditioning compressor can help provide:
- Reliable cooling and temperature control.
- Efficient refrigerant circulation.
- Consistent system performance.
- Suitable capacity for commercial cooling demands.
- Reduced sound and vibration, depending on the compressor type and model.
- Improved control through variable modulation, where supported.
Choosing the right compressor is important for maintaining system performance and avoiding compatibility issues.
The best A/C compressor brand depends on the system, application, and required specifications. Leading manufacturers such as Copeland offer compressors for a range of commercial air conditioning applications.
When choosing an air conditioning compressor, consider the model, refrigerant, cooling capacity, operating conditions, electrical requirements, and available control features rather than choosing based on brand alone.
Scroll A/C compressors use one fixed scroll and one orbiting scroll to compress refrigerant gas. They have fewer moving parts than many reciprocating compressor designs, which can help reduce noise, vibrations, and upkeep.
To choose the right air conditioning compressor, you need to check the system’s technical requirements, including:
- Compressor make and model.
- Refrigerant type.
- Cooling capacity.
- Operating pressure and temperature.
- Electrical supply.
- Compressor size and connection details.
- Required modulation range or control method.
- Whether the system uses a control valve or other control equipment.
